(SALEM, IL) — A 25-year-old registered sexual predator is in the Marion County jail after Centralia police arrested him on drug charges and for multiple violations of the sex offender registry. According to police, Seth Karrer, of Belleville, was arrested after they received reports of a vehicle matching the description of Karrer’s parked near a high school bus stop and on school grounds, and for having internet communications with a child under the age of 18. He was initially arrested for alleged possession of a narcotic drug without proof of a prescription. An investigation into Karrer is ongoing and Centralia police expect he will be facing additional charges. Karrer was convicted in 2013 in St. Clair County on two counts aggravated criminal sexual abuse of a victim between the ages of 13 and 16 – he was 21 at the time of the offense. The conviction placed him on the sex offender registry as a sexual predator. Police say the Karrer case is not connected with earlier reports of children being approached near the junior high and grade schools in Centralia. Karrer remains in the Marion County Jail awaiting the formal filing of charges and the setting of bail.
